How long do zirconia dental crowns last?

The service life of zirconia crowns is usually 10 to 15 years, and the specific length depends on the following factors:

Patients choose materials with better strength or transparency according to their own needs.

2. Manufacturing process

Precision manufacturing: high edge tightness, reducing bacterial invasion, and extending service life.

Rough manufacturing: easy to cause falling off or damage.

3. Doctor’s skills

5.  Use environment

Normal bite force: longer service life.

Excessive bite force: may cause cracking or falling off.

6. Personal habits
